The Negative 40F Aurora Club

While my friends on the east coast are getting pummeled by a record blizzard, here in Fairbanks, Alaska we’ve finally hit “seasonably cold” temperatures. As the mercury dropped On January 25th – 26th to 40 below, the clear skies were coupled with good looking aurora data. The humidity was only at 5% which for me meant perfect clarity to the stars! As I stepped out of the truck I sucked in my first breath of the cold air; it’s always the hardest one! The sting is from both the cold air and the dryness.It bursts into the lungs and bites the nose.

Although this was not my first 40 below night walking around in Alaska, it was the first time I took my camera out into those temps! Shooting at 40 below presented some unique challenges. First, battery life is depressingly short and I could only take about 300 images in contrast to over 1000 on one battery. Second, anything metal is extremely dangerous to the bare skin, and when you are out shooting metal is a common thing! I was carrying a magnesium alloy camera, and aluminum tripod with an aluminum head. Dealing with these items meant wearing liner gloves which resisted the cold like an ant resists a lollipop – I’ve never seen an ant that could resist a lollipop. The result is that I watched the aurora play across the sky in beautiful patterns on several occasions while warming my fingers! Of course, the disadvantage of that is I cannot print my photographic memory, but I still enjoyed a great show as my digits warmed up.  Third, clumsy mits made adjusting a cold, stiff tripod head quite difficult! What did I learn: future cold excursions will include a better pair of gloves!

With my petty whines aside it was a glorious night of aurora and aurora photography. I really focused on composition of shots, and although I did shoot a very short timelapse, most of my night was spent wandering through knee deep powder in the black spruces. Through the night the aurora shifted from an overhead band to the northern skies and danced in vibrant colors. Now that I am indoctrinated, I am looking forward to more auroras in the -40 club!

The other side of the story is the temperatures when I back to the University of Alaska Fairbanks. I was hoping their thermometer would read an official -40, but couldn’t quite reach that. Although at 8:00 AM the sign read -40, so close enough! I’ve included a screen capture of the temperatures and humidity as a some proof as well 🙂

At 1:30 AM the temperatures were hanging around 36 below F (-38C).

Celestial Sights : Comet Lovejoy in Alaska

Comet Lovejoy has been visible in the Northern Hemisphere, but peaked in magnitude on January 15th and is now headed away from Earth. Viewers can still see it with binoculars for probably only a while longer, so get out there soon. It will not be visible for another 8,000 years! Last night I went comet chasing, which I think is the first time since Hale-Bopp! I was just 9 years old at the time, but I remember sitting on the back deck at the house and observing the skies. You may have heard of comets in the news lately. During November 2014, the Rosetta Comet landing (Philae Lander) by the European Space Agency made history as the first time humans have landed a craft on a comet. Some incredible science will hopefully be done once the lander’s solar panels start gathering light again. However, one of the incredible things to come from the observation of the comet was the “sound” that a comet makes. “ESA’s Rosetta probe detected cyclical changes in the comet’s magnetic field environment. To make the comet’s magnetic ‘song’ audible to people, researchers sped up the data 10,000 times its actual rate.” (www.space.com). It has been likened to Predator (the movie), and the similarity is uncanny! The timelapse below includes the eerie and amazing ‘song’!


Comet Lovejoy does not have a huge tail, however is very, very distinctly green. I was told it was green, but the forest/lime green color was much more distinct that I was expecting! Through the night I shot the Lovejoy comet in a variety of methods, I learned a lot! The three images here are meant to give you an idea of where to find Lovejoy current, as well as the look of different focal lengths. At ~300 mm the maximum length of exposure without star trails is about 1.5 seconds.

If you want to get out to see Lovejoy in the next couple of nights let me know. It is worth it!

This image of Lovejoy will give you a good idea of where to look in the skies. The cluster of stars you see is the constellation the '7 Sisters'. On 01/17/2015 the comet was located below, and to the right of that constellation. This image was taken at 17mm, f/2.8, 25sec, ISO 1600

At the Bottom of Winter : Alaskan Tradition

This composite of the sun was compiled from 6 shots throughout the day. Quite beautiful! The composite was compiled in the "Star Trails 2.3" software.

For months we have been losing daylight. June 21st marks a daylight decline which has defined cultures and natural systems in Alaska for millenia.  The short days of winter psychologically effects the mind and  physically alter the body. As it we roll out of our beds the morning after solstice we know that today is just a little bit longer the last! It is uplifting. Until that moment when the days lengthen, the waning light indoctrinates residents into the darkness. You simply get used to doing things in the dark! The changes of daylight we experience now have been celebrated by the traditions of the Inuit and Athabascan people of Alaska; their traditions are symbolic of change and new times. The Athabascan name for the solstice is “dzaanh ledo” which means “the day is sitting”. This description of the actual phenomena that defines solstice is fitting, the day is not gaining or losing time; it is stationary (ttp://goo.gl/cFN613). The Inuit of far north Alaska experience times of no sun at all, and during solstice communities held feasts where shamans prayed for the communities. Meat was eaten by each individual at the same time, and each person eating the meat focused on Sedna. Sedna is a diety of the Inuit underworld and a god of marine animals. After the meat was consumed, water was drank one person at a time in succession, and each person stated the time and place of their birth. To the Inuit this distinguished the summer and winter people. After a trading of gifts, the festivities ended by extinguishing lights in all of the homes which were kindled by a common, newly-lit fire garnering a new relationship with the new sun (http://goo.gl/aRyByZ). Inuit people were able to indentify the solstice when the star Aagjunk (literllaly “sunbeam”) lay directly below the sun which, although unseen, was just below the horizon (http://goo.gl/Rzzttg).

The solstice occurs at 8:30 PM in Alaska, but occurs at different times throughout the world (http://goo.gl/G6QEvw), and rekindles hope that winter is ending and that the new day will be longer.

I shot this timelapse of the Solstice sun on December 19th to give you a feel of the solstice sun (fear not, we only lost 2 more daylight minutes by the 21st). In Fairbanks Alaska, it barely crests the Alaskan mountains (Mount McKinley/Denali visible) before dropping below the horizon again. You can always check out the timelapse of summer solstice when it it never sets in the land of the Midnight Sun. Happy Solstice!

Finals Week Aurora Borealis

It’s finals week here at UAF and that means no sleep because you’re studying… or, because the aurora is out! Last night I simultaneously watched the aurora “oval” (i.e. the prediction of aurora visibility as provided by NOAA Space Weather) on my screen and studied for my evolution exam on Tuesday. When the aurora perked up overhead  at 10:30 PM I abandoned my books, and headed outdoors. For the sake of my education, I decided to stay close to home last night and shoot over the UAF Sustainable Village so that I wouldn’t stay out too late. It was a stunning night to be out!

I am continuing to improve on my timelapsing technique. Last night these images were shot at 1sec with no buffer for card write in the middle. In the past I have left 2 seconds for card write. Often in those two seconds the aurora changes so much that a small gap has been created. You’ll notice without that gap, that the Aurora is silky smooth! Although this isn’t real-time, at 1 second intervals it’s getting pretty close! The 1 second exposure captured the vertical banding of the high aurora well.

Here is the timelapse from the night:

And, here’s the imagery.

Leonid Meteors, Aurora Borealis, Angel Rocks, Alaska!

We shut the truck off and stepped out into a cool night and a light breeze which shocked the face. My friend Ross and I were after auroras, and we planned to summit Angel Rocks in the Chena Recreation Area to spend the night and watch it. The sun was low in the sky as we started up the 1.6 miles to the summit of Angel Rocks. By the time we had reached the top of the ~1000 foot climb, the breeze funneling up the canyon below had stopped, and the sun melted into the horizon leaving a blue and gold light which lingered for hours. With short days in Fairbanks, it was hard to forget it was only about 5:30! There was a lot of night to go.

I was delighted to find a cave at the top of Angel Rocks. It was two ended and had large crevasses in the ceiling to view the stars. In the middle I could stand all the way up, and the larger south facing entrance was almost 8 feet tall. I’m just speculating, but I think this cave was formed as a magma bubble. The geology of the summit was far different than any geology I had seen in the Fairbanks region. In contrast to the normal scree slopes and shale of the region, the exposed rocks were granite and had forms which suggested bubbling magma. The rock outcrop where we stood was very unique!

The cave at the top of angel rocks was amazing! The double entrance was passable and you could easily stand up inside. Here is a picture from out of the cave looking south. You can just see the tail of the milky way.

The Leonids

In a collision of natural phenomenons, the Leonid meteor shower lined up with an incredible aurora display. Each year the Leonid meteor shower peaks around the 17th or 18th of November. Named after Leo, the constellation that they seem to radiate from. The Leonids Meteor Shower is actually small pieces of the comet Tempel-Tuttle which burn up as they enter our atmosphere.  Incredibly, the size of the majority of particles range from grains of sand to pea-size.The largest meteors are often only marble sized pieces of comet. That’s a lot of light from a particle the size of your favorite shooter!! These particles burn up because the air in front of them is compressed and heated which scorches the meteor. That’s way different than I was ever taught (i.e. they burn up because of friction with the air). How fast do they have to be moving to build up that air pressure? The particles can enter the upper atmosphere at 160,000 mph! The Leonids were 24 hours from peak activity, and throughout the night they dazzled us with frequent and long tails.

The Aurora

As the sun set the aurora immediately started up. In fact, with an ‘official’ start time of 5:30 PM it was the earliest I have ever seen the aurora appear! It certainly seemed to be a good omen for the night to come.

The aurora had already 'booted up' as the sun set. That's an incredible show of energy!!

Over the course of the night we enjoyed three bursts of incredible aurora. From 5:30 – 7:00 PM, 9:30 – 11:30 PM and from 5:30 – 6:30 AM. Although sleeping in the cave would have been VERY awesome, the night was so warm that I was content to roll out my sleeping bag under the stars and slumber around midnight. I awoke at 5:30 AM not minutes before an incredible corona dominated the overhead skies (captured in timelapse!). I think my aurora sense was tingling and telling me to wake up!

This capture of the aurora over Angel Rocks, Alaska pretty much says it all. The lone spruce, rock outcrop and rich aurora all make for an amazing shot!

For the second night in a row the aurora put on an unforgettable show. I think the aurora are like fingerprints. They may look alike, but none are ever the same! For its immense status in the sky, I had never seen aurora that stayed as intense as this one. At times you could have read a book by it, and all through the night the sky was filled with incredible beauty and auroral ballerinas. In Minnesotan, it was “oofda good!”.

Experiencing the Aurora Borealis in Denali National Park

This last week has been really amazing in regards to the weather in Fairbanks, Alaska. While my Minnesota family and friends hunted whitetails in 20 degree weather, we enjoyed temperatures nearing 30 degrees all week. To boot, it was sunny, you betcha! The Geophysical Institute forecasted high aurora activity starting on Friday night the 14th and extending all the way through Monday! With the warm weather, and aurora forecast it was just a matter of deciding where to go!

Panav, Logan and I arrived at the gates of Denali National Park at 9:30 PM. The winter regulations only allowed us to drive in 3 miles, and from there we packed our gear another 1.5. We located a place where the black spruces were shorter, and the mountains stood tall around us. The heart of Denali Park was absolutely dark, and as far as I know we were the only ones in the park that night! Meteors from the Leonid meteor shower flashed overhead leaving their long trails and thrilling the watchers on earth. This shower peaks on 11/17/2014 – so be sure to check it out if you have some clear skies tonight! Over the mountains, the aurora was already building as our three shutters started popping, and we did not have to wait long for the lights to explode around us. Energy of the northern lights always seems to originate from on horizon, and on this night the jagged horizon in front of us swelled with an intense green light that erupted overhead throwing pinks and greens in racing lines overhead.

The building aurora over Denali had a real treat in store for us! It was almost a year ago that I posted about my first “incredible” (I use quotations because they’re all pretty amazing) aurora, and I tried to explain the corona of the aurora. Officially, it is defined as “a circle of light made by the apparent convergence of the streamers of the aurora borealis” (MW Dictionary). My analogy was to think of single beam of the corona as a pencil, which you balance on your nose and then concentrate on the eraser; the corona is made of hundreds of green, red, and pink ‘pencils’! It is fast moving and pulses with energy. I am happy to say that I’ve captured a corona on timelapse for the first time!

Before leaving you with the the timelapse and images from the night I would like you to know I now have a page on Facebook, come check it out and follow along : www.facebook.com/ianlww. Thanks all!

Red Sky at Night : Aurora Delight!

The incessant baying of sled dogs, a starlit night, and a beautiful red aurora. When I went out to Black Spruce Dog Kennels to capture the aurora I was waiting for the effects an X-flare to hit the earth. Two days before the sun had let loose one of it most powerful class of flares. Even though the flare was not directly headed to earth, the ejected plasma was expected to react with our earth’s magnetic field and cause some auroras! My goal for the night was to tie together two cultural pieces of Alaska – dog mushing and the aurora. Incredibly, the aurora started showing up on my camera at 6:00 PM on my camera along with the moonrise. On an ‘ordinary’ night the aurora will begin at 10PM – the early aurora was a good omen for what was to come!

From a technical standpoint this is one of my favorite auroras I’ve captured. The stars were pin-point sharp and as you’ll see the pan over a dog-sled adds a ton! Shooting over the activity of the dogs was a lot of fun – but I had to leave so they would kennel up. If you have ever been around a group of sled dogs they bark, bay, and howl when strangers are around!

Artistically, the reds are some of the nicest colors I’ve captured. They only appeared for about 25 minutes during the night, but it was stunning! Sitting under the aurora, I thought of the old adage “Red Sky At Night, Sailor’s Delight”, and thus the title of this post was born!

I arrived home at 5:00am and the aurora was still dancing over the Sustainable Village. I snapped a couple of captures for finally calling it a night, which you’ll see below. Overall the aurora was visible for 12 hours due to the x-flare activity!

The timelapse video here captures the reds of a beautiful aurora and a little slice of life at the Black Spruce Dog Kennels.

An Industrial Aurora Over the University of Alaska Fairbanks

In Fairbanks, even when you can’t get out into the real ‘dark skies’ of Alaska (for instance, last night I had to work :|) you can still enjoy the Aurora. Although I would prefer to shoot the aurora in pure darkness, the effect of moving cars and the moon tracing across the solar panels located near Cold Climate Housing Research Center is actually pretty cool! This footage was shot just down the road from where I live at the UAF Sustainable Village. This footage was shot over the University of Alaska Fairbanks on 11/06 – 11/07/2014. I hope you enjoy!

Raising a Yurt in Fairbanks

This last weekend I had the privilege to add a new skill to my construction resume when I and group of dynamic and great individuals put up a round, vinyl sided house called a yurt. If you are now thinking to yourself “a vinyl sided building in a landscape where temperatures can reach 50 below??… that’s crazy!” your thoughts are actually right on track, it’s a little bonkers. However, with the proper heat and insulation yurts can be a warm and comfortable way to get through life in the Interior.

The construction day was marked by beautiful skies, great company, strong coffee, pizza, and some local brew. I’ll head into some details of yurts (if you’re into that kind of thing, and I’m just learning for the first time), but first, here’s the timelapse of the day. I think the timelapse is pretty fun!

The yurt is originally a Mongolian structure associated with nomadic horse herders of Mongolia .and appeared for the first time in records near 500 BC although yurts have likely been around since 1000BC – that’s quite awhile! (although, to put it in perspective, Bristlecone pines may be 5000 years old, meaning they germinated ~3000BC). The structure is easy to take down and move which benefited the lifestyle of the Mongolian horse herder.

As you construct a yurt you, the builder, quickly gain appreciation for the efficiency of the dwelling. It is amazing that 6-8 untrained people could put up the bulk of the structure in just 8 hours! This yurt (http://www.nomadshelter.com/) was constructed on a raised platform with the about 10 inches of foam in the floor providing rigidity and insulation (~R50). The windows and doors were framed, and lathe which supports the walls was stretched between each of the frames. Stretched on top of the lathe a 3/8 cable hooked onto 2×4 rafters which joined into the central ring at the peak of the building. The tension of the boards on the cable holds the whole thing up; we found that 2 guys could sit on the peak with no stress the the building. It’s amazing that with NO nails you can support the weight of 300 pounds of man!

Once the rafters are on, the roof insulation and cover are put up and extra insulation is stuffed into the roof cavity. The walls are hung and insulated and finally the outer cover is put on. Adding in a few windows, a door, a roof cap with a stove pipe, and a stove will ensure your yurt is ready for the Fairbanks winter!

The images below were taken by Chris Behnke, the yurt owner. They show up close some of the key pieces of the yurt.

In the center of the platform a scaffolding was built and the center ring was suspended.

The yurt had windows and doors framed first. The tops of the framing lined up with the lathe walls and a cable was strung in a circle around the top. That cable supported the roof rafter boards and vinyl.

So, the next time you’re at local ski resort and they put you up in one of these round, wonderful buildings you are now equipped with all sorts of conversation starters 😉

The Chena River Aurora

Ice-up will be happening any day now in Fairbanks. The small ponds and marshes have been locked with ice thick enough to walk on since the end of September, but the rivers have resisted a solid state owing to a not-too-cold October to date. However, in the Interior it seems that 40 below could only be the next day away!

I took the opportunity to find a new aurora watching spot. My goal was to shoot over an open river. I headed to the Chena Lakes Recreation area and found my view at the Granite Tors campground. The North Fork of the Chena was running, snow-covered and beautiful! As I walked up it’s banks I was a bit on edge however. On a moonless night at 12:00 AM in Alaska, moose look the same as the inky blackness. Although they shouldn’t pose any real danger this time of year – they just want to get away – I was not looking to be scared tonight! However, in dramatic fashion a cannoning KAPLOOSH echoed up the river, and the source came from the river only ten feet away from me. A beaver, out for a midnight swim announced its presence and effectively scare me into nearly dropping a load! Lol, nights in Alaska.

The rev of the aurora engine was a bit slow right away, but a broad overhead band suggested that sometime during the night the show could be spectacular! At 12:45 AM the broad, undefined band erupted into curtains of pink and green (another example of Why The Aurora Flares Up). A hint of blue shimmer lit up far edges of the aurora in space. Overhead they danced and danced. The timelapse here captures the night. I have continued to  develop new video editing techniques, and I think some of the motion introduced in this particular timelapse is pretty effective, but I would love to know what you think!

Just as a little fore-shadowing I spent yesterday putting up a friend’s Yurt. It was great, and I shot a fun timelapse of that. More on that soon! 🙂

Here’s a gallery of some images from the night. Be sure to click on them to expand. Thanks for checking in!
